Question

Joanna claims that a large block of ice will cool a substance more than a small block of ice will at the same temperature. To support her claim, Joanna places two blocks of ice, one larger than the other, into separate beakers each containing some water. She compares the final water temperatures of the two beakers after each block of ice has melted.

Which change to Joanna’s procedure will provide better evidence to support her claim?


Multiple choice question.


A)
She places each block of ice into beakers of different sizes, each containing different volumes of water.


B)
She places each block of ice into beakers of different sizes, each containing 2000 mL of water at the same temperature.


C)
She places each block of ice into identical 3000 mL beakers, each containing water at different temperatures, and measures the temperature before and after adding the ice.


D)
She places each block of ice into identical 3000 mL beakers, each containing 2000 mL of water at room temperature, and measures the temperature before and after adding the ice.

Answer 1

Answer:

30000 ml beakers

is answer

Answer 2

Joanna’s procedure will provide better evidence to support her claim because, she places each block of ice into identical 3000 mL beakers, each containing 2000 mL of water at room temperature, and measures the temperature before and after adding the ice would provide better evidence to support her claim.

Option D) She places each block of ice into identical 3000 mL beakers, each containing 2000 mL of water at room temperature, and measures the temperature before and after adding the ice would provide better evidence to support her claim.

This procedure controls for the variables of the size of the beaker and the initial temperature of the water, allowing for a fair comparison between the effects of the different sized blocks of ice. By measuring the temperature before and after adding the ice, Joanna can determine the temperature change and compare the extent of cooling produced by each block of ice. This will provide more direct evidence to support her claim that a larger block of ice will cool a substance more than a smaller block of ice at the same temperature.
